However, in some special cases in the clinic, induction intubation is not possible, and conscious intubation is required. The conscious trachea cannula is usually required to perform oropharyngeal and subglottic anesthesia, and the superficial anesthesia is to apply local anesthetic with strong penetrating power to the surface of a mucous membrane so that the local anesthetic penetrates the mucous membrane to block nerve endings under the mucous membrane, so that the mucous membrane generates an anesthesia phenomenon, and the intubating reflex of a patient is relieved.
The clinical methods for oropharyngeal and tracheal anesthesia include thyrocricocentesis and laryngeal nozzle surface anesthesia. However, the perionychus puncture tracheal anesthesia is a traumatic operation, and can cause fear, pain, severe cough, tracheal injury, intratracheal hemorrhage and other adverse stimuli to patients. And the larynx spray tube can't carry out the surface anesthesia to oropharynx portion and glottis accurately because plasticity is relatively poor to greatly reduced the surface anesthesia effect, lead to patient relatively poor medical service experience when carrying out the clear-headed intubate, increase patient uncomfortable sense. Therefore, how to explore a novel, reliable and efficient surface anesthesia method has important significance for improving the medical service quality and the medical experience of patients.
